Listened to Darren’s podcast with Dr. Robert Edwards..https://thecoopervortex.podbean.com/e/db-cooper-and-flight-305-dr-robert-edwards/
Overall very good, agreed with nearly all of it. Obviously there is more in the book.
Some notes, mostly agree, some minor additions.
Absolutely, easily survivable jump.
Cooper had jump experience, military.
Oscillations were felt for most of the trip, the report of oscillations was a rapid increase of needle fluctuation on the gauge which ended with the bump felt in the ears. That bump was simultaneous with the gauge needle at the extreme. Essentially, the bump being simultaneous with an extreme needle oscillation which would have occurred in seconds not minutes.
305 stairs were not locked down. The light was red/amber, red/amber is unlocked. Green is down and locked, no green light noted. Further, the stairs would have been damaged during landing if locked down, the damage was only minor scrapes on the end.
The Placard was not inside Norjak. 100% fact. I have a photo. There is no debate, it came from the outside of a passing 727/737.
The parachute description came solely from Cossey, he is a proven liar and unreliable.
The wind at the LZ was an estimate. Reconstructing the wind drift is valid.
The flighpath had a plotting error of 1 mile, it is in the FBI files. In 1973 they discussed recalculating with a 0.5 error using a new method.
The common plotted flightpath is generally accurate along v-23 with that 1 mile error consideration.
The Dan Cooper magazine was not published in english, but it was published in Mexico in Spanish for Latin America. The French language angle is a red herring. Since Cooper was desribed as Latin/Mexican that becomes more significant. Hahneman worked for the IGY in Latin America which was sponsored by Herge, the Dan Cooper publisher. So there is a connection but I agree the probability is still low, so Darren's comic connection may still be alive, barely. I also have a more likely source for the Dan Cooper name..... NASA.
True, the TBAR money most likely came from the River upstream. Although, I did find that the mouth of the Lewis was dredged and dumped above TBAR. One of my theories has the money entering the Willamette.. another the Columbia but the Willamette has a gravel bottom vs the Columbia with a sandy bottom.. if anybody could do an abrasion test for the rounding of the packets that might help.
The problem with the FBI/files as data.. there are errors, these are not conclusions but research notes. So, they have a built in error potential.
